Very nice product. Sturdy and well made. My 200 lb husband can sit on block with only a small indent in foam. I like that it isn't attached and you can make different "courses". My 5 year old plays with it as much as my 1 year old. My only issue is that the block is really tall. Wish it was about 4 inches shorter. I would like the 1 year old to play on it without worrying about him falling.
